Serious question: Why don't EVA suits have an emergency air-straw?
I know that drowning is one of the biggest risks on EVA (water leaks, coolant leaks, vomiting, etc), and I would have assumed that the simplest safety feature would be a simple tube that the astronaut could reach with their lips, and would provide enough air to live, even if the helmet otherwise filled with liquid.
Is there some technical or practical reason why they don't?
